Umehluko omkhulu phakathi kwezitini zokufaka i-mullite nezitini eziphikisayo zimi kanje:
Ukusebenza kwe-1.I-insulation: I-thermal conductivity yezitini zokufakelwa ngokuvamile iphakathi kuka-0.2-0.4 (isilinganiso sokushisa esimaphakathi 350 ± 25 ℃) w/mk, kuyilapho ukuqhutshwa kokushisa kwezitini eziphikisayo kungaphezu kuka-1.0 (isilinganiso sokushisa esingu-350 ± 25 ℃) singaphetha ngokuthi ukusebenza kwe-insulation kungcono kakhulu kunokufakwa kwezitini. izitini ezisebenzayo.
2. Ukumelana nomlilo: Ukumelana nomlilo kwezitini zomlilo ze-mullite ngokuvamile kungaphansi kwama-degree angu-1400, kuyilapho ukumelana nomlilo kwezitini eziphikisayo kungaphezu kwama-degree angu-1400.
3. Ubuningi:Izitini zomlilo ze-Mullitengokuvamile izinto zokuvikela ezilula, ezinobuningi ngokuvamile obuphakathi kuka-0.8 no-1.0g/cm3, kuyilapho izitini eziphikisayo zinokuminyana ngokuvamile ngaphezu kuka-2.0g/cm3. Ngokuvamile, isitini esiphikisayo sinamandla amakhulu emishini, impilo ende yesevisi, ukuzinza okuhle kwamakhemikhali, akukho ukusabela kwamakhemikhali ngezinto zokwakha kanye nokumelana okuhle nokushisa okuphezulu. Ukushisa kwayo okuphezulu kokumelana nokushisa kungafinyelela ku-1900 ℃. Ilungele iziko lokushisa eliphezulu neliphansi lokushisa, ama-reformers, ama-converter e-hydrogenation, amathangi e-desulfurization, neziko le-methanation ezitshalweni zomanyolo, idlala indima ekuhlakazeni igesi noketshezi, ukusekela, ukumboza nokuvikela ama-catalysts. Ingasetshenziswa futhi kuma-hot blast furnaces kanye nemishini yokuguqula ukushisa embonini yensimbi.
Izitini eziphikisayo zinezinzuzo zokuminyana okuphezulu, amandla aphezulu, ukumelana nokugqokwa okuhle, ukumelana nokugqwala okuhle, i-coefficient ephansi yokwanda okushisayo, ukusebenza kahle kokugaya okuphezulu, ukuncishiswa komsindo okuhle, impilo ende yesevisi, izinto ezingangcolisi, njll. Kuyizinga eliphezulu lokugaya elifanele imishini ehlukahlukene yokugaya.
Umehluko phakathi kwezitini ze-refractory nezitini zomlilo ze-mullite zibalulekile, njengoba indawo yazo yokusetshenziswa, ububanzi, kanye nomsebenzi kuhlukile. Izinto ezihlukene zizosetshenziswa ezimeni ezahlukene. Lapho sikhetha izinto zokwakha, sidinga ukunquma ukuthi iyiphi impahla ephikisayo efaneleka thina ngokwethu ngokusekelwe esimweni sethu sangempela.
